Page 8: Safety Considerations
This device is marked with the international Caution symbol. It is important to read this manual before installing or commissioning this device as it contains important information relating to Safety and EMC (Electromagnetic Compatibility). Unpacking & Inspection Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate the unit if damage is found. - Page 9 SAFETY NOTE: Disconnect all signal input and outputs before attempting this procedure. Instructions 1) Open the Signal Conditioner Unit—Remove Side Covers from Unit by lifting at the “angled corners” first, using a flat-head screwdriver. Continue detaching remaining edges of the Cover. 2) Short TP6 &...

Page 10: Commands For Accessing Eeprom
COMMANDS FOR ACCESSING EEPROM: command letter index NOTE: Data (Number of hex digits) = 2 * number of bytes command letter "W" commands should be followed by "Z01" command for new values to take effect. COMMAND FORMAT (TRANSMITTING): *[nn]Cxx[data][hh]<cr> Note: Data is required if Command Letter is “W” RESPONSE FORMAT (RECEIVING): Correct response : If unit is in echo mode* (see "BUS FORMAT") :... - Page 11 If unit is not in echo mode : i. For the commands which require the data to be transmitted by the DRX Signal Conditioner, data is sent in the following formats: data[hh]<cr> ii. For the commands which do not require the data: NO RESPONSE Error response: 1.

Page 12: Description Of Data
Special code indicating an error has occurred as: <cr> Carriage return Note: If Baud rate, Recognition character or address are not correct then the UNIT will not respond. DESCRIPTION OF DATA : For the following Bit Pattern. The LSB is always bit 0. Bit numbers are always counted from right to left, with the rightmost digit being bit 0, and the next to the left would be bit 1. - Page 13 b. INPUT RANGE BIT NO. VALUE Bits: c. INPUT RANGE BIT NO.

Page 15: Decimal Point
Note 1: Bit 2&3 set the speed of process totalize. The time it would take process totalize to reach the non-totalize reading is shown in the following table: Bit 3 3. DECIMAL POINT : This is one byte (2 characters) as: value meaning XXXXXX. -
Page 16: Communication Parameters
5. READING SCALE: Multiplication factor applied to input to get a higher or lower reading. This is 3 byte data (6 characters) as follows: - Bits 0 to 18 (19 bits) are value of the scale from 0 to 500000 - Bit 19 is sign, 0 for positive and 1 for negative - Bits 20 to 23 are for decimal point value = DP It means as:... - Page 17 PARITY = bits 4,3 and are: DATA BIT = bit 5 and is: STOP BIT = bit 6 and is: Bit 7 : always 0 Note 1: Stop bit is always 1. Unless 7 data, no parity is selected then unit will use 2 stop bits. Note 2: When 8 Data bit is selected, only NO PARITY is allowed.

9. DATA FORMAT: This is one byte and specifies the data which will be transmitted against the "V01" command. Bit pattern: bit 0 = 0/1 Means do not include/include peak & valley status register. bit 1 = 0/1 Means do not include/include reading. For models(TC/RTD/ACV/ACC): bit 2 = 0/1 Means do not include/include peak reading. - Page 19 12. UNIT OF MEASURE: This is 3 bytes. It is ASCII value of unit of measure. 13. GATE TIME(For FP model only): This is 1 byte from 00 to FF. For value = 00 to FA: Each count equals 10ms. If 0 then gate time = 3ms. Example : 1 second gate time = 64 hex.

COMMANDS FOR MEASUREMENT VALUES: Command Receiving value *01X01 (For all models): Note: In order to have continuous update on reading. Customer should send X01 command every time reading is requested. Models(TC/RTD/ACV/ACC): *01X02 Peak reading value. *01X03 Valley reading. Models(PR/ST/FP): *01X03 Peak reading value. -
